Physics Momentum Problem and Moments?

A heavy car A, of mass 2000kg, travelling at 10m/s, has a head-on collision with a sports car, B, of mass 500kg. iF both cars stop dead on colliding, what was the velocity of B

According to law of conservation of momentum, the total momentum before and after collisions must be conserved.
so 2000*10 + 500* (Vel. of B) =0
solving the equation we get,
vel. of B is = 40 m/s

2000*10=500V2
v2=40 m/s
